Bostik PES 376 Low Temp Technical Lamination Copolyester Hot Melt

Bostik PES 376 Copolyester Glue for Low-Fusing Temperature Fabric Laminations

Bostik PES 376 is a low-fusing thermoplastic copolyester adhesive engineered for textile lamination, technical fabrics, and apparel construction. Its reduced fusing temperature supports bonding to heat-sensitive substrates while enabling fast production cycles. PES 376 delivers good adhesion to foams, metals, PVC, fiberboard, and microfiber materials, and maintains strong bond integrity through washing, dry cleaning, and steam exposure. Available in powder and pellet formats, it's well-suited for dot coating, scatter coating, and other lamination techniques used in clothing and garment manufacturing.

Bostik PES 376 Low Temp Lamination Glue Advantages

• Low Fusing Temperature: Activates at glue-line temperatures between 266–302°F (130–150°C), enabling bonding to heat-sensitive materials.
• Broad Substrate Compatibility: Bonds to foams, metals, PVC, fiberboards, and microfibers used in apparel, clothing, and technical laminate systems.
• Good Washing and Dry Cleaning Resistance: Maintains adhesion through laundering at 140°F (60°C) and standard dry cleaning cycles.
• Steam-Formable: Withstands steam exposure during garment shaping and textile finishing.
• Multiple Formats Available: Supplied in both powder and pellet form, with particle sizes for paste dot, powder dot, and scatter coating.
